Daniel Akinwunmi will portray the protagonist Jack Stone because the director has seen his acting ability in other school plays and knows Daniel can convey the required emotions. Loretta Gleeson will play Doctor Thompkins since she is an assistant headteacher familiar with delivering difficult news, so the role will not require much acting. Asad Ilyas will play the thug Dwayne due to his ability to make people uncomfortable, and because the role requires little dialogue or acting experience.
